Corner Radius End Mills

Corner radius end mills combine the profile of a square end mill with a small protective radius at the cutting corners, improving edge strength and tool life in demanding machining conditions.

  • Best for: harder materials, abrasive materials, and applications involving interrupted cuts
  • Why choose it: the corner radius reduces edge chipping and stress concentration, extending tool life compared to sharp square ends
  • Common uses: general machining, pocketing, and semi-finishing passes where durability and consistent edge quality are more important than sharp internal corners
